vascular supply Flashcards
how many anterior longitudinal spinal a are tehre
one
how many posterior longitudinal spinal a are there
two
feeder/segmental spinal arteries arise from
vertebral and deep cervical a
posterior intercostal a
lumbar a
posterior intercostal a are from
descending thoracic a
lumbar a are from
descending abdominal aorta
feeder/segmental a enter the vertebral canal through the
IVF at every single vert level
the segmental spinal a give rise to
anterior radicular a
posterior radicular a
the radicular arteries follow and supply the
anterior and posterior roots of the spinal nerves
at various vertebral levels, the segmental spinal areties also give off
segmental medullary arteries
the segmental medullary arteries pass () to the () vessels reinforcing these vessels
directly, longitudinally
artery of adamkiewicz arises in the () or () usually on the ()
lower thoracic or upper lumbar region, on the left
what artery reinforces the arterial supply to the lower portion of the spinal cord including the lumbar enlargement
artery of adamkiewicz
whats the venous drainage of the spinal column
superior vena cava and inferior vena cava plus the other veins that are same as arteries
pial artery
off of anterior long, meshy network in pia mater that supply cord
